The density of monopoles in spin ice can be enhanced by rapid cooling. After the creation of significant numbers of monopoles, magnetization measurements show that, much like charges in an electric field, monopoles can be driven by a magnetic field.
Experiments in microfluidics reveal long-range orientational correlations in the velocities of flowing droplets that can be rationalized in terms of an analytically solvable model.
The no-cloning theorem is challenged by super-replication, a process that takes a number of copies of a state and produces a quadratically larger number of exponentially close-to-perfect copies — the catch being the low odds of success.
